Dynamic DNS or DDNS is a mechanism to update a DNS hostname (like myname.dyndns.org) with your current IP address so that when you type in myname.dyndns.org, it will always resolve to your IP address regardless of whether it changes.

Software Update Client

This is our most preferred update mechanism. We maintain software clients for Windows and OS X and have worked the developers of two *nix update clients to refine their behavior. You first need to create an account and create a hostname before you should set up the update client.

Hardware Update Client

Over the years, many router manufacturers have embedded dynamic DNS update clients into their devices. Everything from high-end Cisco routers and Juniper firewalls to entry level access points and everything in-between. DynDNS.com is always working with these vendors to improve their standards compatibility and certify devices. We already have a good list of DynDNS.com certified DDNS routers.

How to get started

If you want to set this up, all you need to do is create a DynDNS.com account, create a DNS hostname, and setup an update client. Create an Account.
